I see plenty of sub builds, and I plan to build one myself, but I am just starting to put together my theater room, and am needing surrounds first. I have just purchased a Yamaha 663 and have some older Pioneer towers (12,8,4,tweet each) that I will use for fronts for now. The question is... is it worth building your own surrounds and center or can you buy them for about the same price for the same quality you could build? I don't see alot of builds like this, and I wonder what the reason is. If you suggest building what are your suggestions as to what speakers to use and where to buy. The room is 16X17.
